Looking for an ESL teaching job. (Istanbul)

Dear Members, I'm Canadian and I have been teaching English in Bangkok, Thailand. It was a fabulous experience! However, I would like to relocate to either Izmir or Istanbul. I am interested in teaching English within a medical / health care context or a private school. I am wondering if anyone could please provide me with any reputable contacts or connections that might be able to assist me in finding an ESL teaching position. Where is a good place to start? Thank you so much!
